1-1/4 inch X Close Galvanized Steel Nipple

1-1/4” Galvanized Steel Nipple – Threaded Fitting for Corrosion-Resistant Pipe Extensions

The 1-1/4” Galvanized Steel Nipple is a threaded pipe segment designed for extending pipe runs or connecting two female-threaded fittings in fluid transport and mechanical systems. Manufactured from schedule 40 steel and hot-dip galvanized for added corrosion resistance, this nipple is suitable for use in potable water lines, low-pressure steam systems, and general utility piping.

This fitting supports high mechanical integrity in above-ground installations where protection against rust and abrasion is critical. Its uniform threading meets ANSI B1.20.1 standards, ensuring compatibility with common malleable iron, cast iron, and galvanized steel pipe fittings.

Product Specifications

Key Features

• ✅ Corrosion-Resistant Surface – Zinc coating protects base steel from oxidation in wet environments.
• ✅ Thread Integrity – Machined NPT threads provide reliable sealing with approved thread sealants.
• ✅ High Mechanical Strength – Capable of withstanding moderate internal pressures in HVAC and plumbing systems.
• ✅ Versatile Application – Compatible with a wide range of piping systems including water, air, oil, and non-corrosive gases.
• ✅ Code-Compliant – Manufactured to meet applicable plumbing and mechanical codes for galvanized piping.

Common Applications

The 1-1/4” galvanized nipple is widely used in commercial, industrial, and residential piping systems. Common installations include water distribution systems, outdoor spigots, compressed air systems, and mechanical piping frameworks. Its corrosion-resistant coating makes it suitable for exposed installations in basements, garages, or service rooms.

Installation Considerations

Threaded pipe joints should be tightened using standard pipe wrenches. Pipe thread sealant (such as PTFE tape or pipe dope) is required for sealing and to prevent galling during assembly. Do not overtighten to avoid distortion of threads or stress-induced cracking.

Note:

Not intended for use in underground applications or with highly acidic/corrosive fluids. For buried or aggressive chemical applications, use epoxy-coated or stainless steel alternatives.

This 1-1/4” galvanized steel nipple offers consistent performance and long service life in standard piping systems. With precise threading and a galvanized finish, it delivers the strength and corrosion resistance expected in professional installations.
